[HTC Sensation] baadnewz:
well if ain't broken don't fix it :)
[HTC Sensation] vincepg13:
I tried always on dual core and being brutally honest I don't think its worth it. I think HTC got it right by kicking the second one in only when its needed, i drained 60 percent battery in under two hours with it on :/

I just wish we could apply governors and CPU speeds to cpu1 and have them stick, and the possibility to lower the threshold for when it kicks in would be Kool...I know the dude that made the dev dual core thread is working on this with other people so not to long to wait hopefully. And baad & one of his people is working on smartass2 so all good.

So baad please don't go down the route some roms are going enabling full dc, sometimes stock is best, and if you do then a patch to revert back would be appreciated :)
[HTC Sensation] HashTagHell:
Try this one I attached.
[HTC Sensation] GabrielSousa:
the script its with interactive ,

test it with smartass.... i prefer the interactive...

did anyone test the script ?
[HTC Sensation] Kupfel:
Is there even anything at all that uses both cores? I think it's a totally senseless killing of battery life at this point. ice cream sandwich will probably change that but right now...
[HTC Sensation] baadnewz:
there is dual core support without that script.

it works like this, most of the time cpu1 is offline due power saving. but when cpu0 is full load cpu1 goes online with ondemand governor.

now that script keeps both cpus online from 1st boot in order to change cpu1 governor.(you cant change governor or freq when cpu is offline).

unless all you care about is scores i dont suggest using that script because battery life will be shorter. asmp hot plugging in this case is used to power saver

p.s. this is the shorter explanation after one too many drinks, so if you don't understand no biggie :)
[HTC Sensation] vincepg13:
Yes we understand, and I'm thankful you've kept it how it is and decided not to use these scripts
[HTC Sensation] GabrielSousa:
baadnewz is right ;)

but for those who wanna test it,

i made 2 flash zip

1 zip for smartass scaling_governor

and other zip for interactive scaling_governor

you can always delete the file /system/etc/init.d/98dualcpu

EDIT:

change the smartass script
[HTC Sensation] rawrfische:
Hmm I don't think I like the idea of CPU1 coming alive when I'm say... looking at text messages or browsing the internet. My FPSE sessions might benefit from this, but I dunno.

I'm more curious to see what Faux, Cayniarb, morfic, BrokenWall, etc., have been up to. It sounds like they are going to have a more practical solution soon. Going to mess around with Faux's 2.3.3 kernel a little later today. And then there's smartass2! It's going to be nice to have so many options. :)

Ok, back on topic. I did the EU 1.45.401.2 RUU + IC 2.2.5 flash earlier this morning. Still too early to tell about battery life, but my phone seems to have suffered no ill effects. Since I'm on TMOUS, would it have been better to flash the TMOUS 1.29.521.2 RUU, run the latest OTA and then flash IC 2.2.5? Did I miss out on any important files by using the EU version? I thought about doing it with the TMOUS files, but it was 4am and I hadn't slept yet.
[HTC Sensation] vincepg13:
Well they use the same radio don't they so all should be good, whole point of super cid I guess
[HTC Sensation] rawrfische:
Yea, the radio I figured would be ok.

I was more concerned with the firmware and drivers that get flashed to all of the other partitions that are unaffected by flashing ROMs. I guess a Sensation is a Sensation though. The hardware inside our phones can't be all that different from EU to US?
[HTC Sensation] baadnewz:
you can't use smartass for cpu1, system won't boot

try to enable smartass for cpu1 within shell.. see what happens
[HTC Sensation] gokberks:
How can i overclock with new kernel unity v7 kernel?

Edit: the app virtuous overclock doesn't work on me. it says force close
[HTC Sensation] GabrielSousa:
thanks, i will change the script
[HTC Sensation] vincepg13:
Just an extra antenna I believe
[HTC Sensation] vincepg13:
Wasn't ondemand the only governor working prop with CPU1
[HTC Sensation] umd:
Baad, I know it might be weird but could you include this mod which disables the half-carousel effect that appears after every unlock? Like Romanbb's ROM :D

[HTC Sensation] baadnewz:
damn, ill do some tests then pronounce about it!
[HTC Sensation] LeeDroid:
No noticable difference in drain dude, I put the script together last night, running interactive on both cpu0 & cpu1

Sent from my s-off HTC sensation running LeeDrOiD Sensational
[HTC Sensation] baadnewz:
Any noticeable difference in performance?
[HTC Sensation] LeeDroid:
I personally think so but hey, could be the placebo effect lol

[HTC Sensation] baadnewz:
doing the experiment myself tonight :))
[HTC Sensation] baadnewz:
since is better to have multiple feedback

who is willing to try:

http://www.multiupload.com/VVVIXGGUAA

flash from recovery

observe:

1. performance is better than before

and

2. battery usage is higher or not
[HTC Sensation] lamecake:
Does this require the stock kernel to be flashed first?
[HTC Sensation] baadnewz:
will work on any kernel but is best to be tested on stock
[HTC Sensation] mexxxico:
Confirmed by more than appreciable difference in speed... :)

For battery power, I will need more time...
[HTC Sensation] hoevito:
I have definitely noticed a speed increase as well, battery does seem to be draining a little quicker tho...but the performance improvement is pretty nice...
[HTC Sensation] schidddy:
gonna try but if u gonna spend a revert back to normal zip :)
[HTC Sensation] rawrfische:
Yikes! My frames per second on FSPE (PSX emulator) have improved drastically. That alone has made the patch worthwhile for me.

Regular homescreen usage seems the same but it was already fast on IC 2.2.5., so it's hard to say.

Too early to say anything about battery life on this patch. Will keep an eye on the battery and report back in a day or so.

/edit

CF-Bench hates my phone on this patch. But I don't care. Improved FPSE framerate is much more important to me than some silly bench numbers.
[HTC Sensation] mexxxico:
To restore the original state just delete 10optimize from /system/etc/init.d/
[HTC Sensation] schidddy:
thanks m8, one question though... Could this be dangerous as i read somewhere that it could harm the phone if both cores are running all the time or am I missing something?
[HTC Sensation] Dexter666:
What to do if Market isn't download anything, just bar keep running at 0%?

Clearing market cache didn't helped. Phone restart is helping only for first download from market.
[HTC Sensation] ziggimon:
I've had issues with bad WiFi connection causing this. Where WiFi states its online but the data stream to my WiFi accesspoint is not working. I have free data, so I just turn off WiFi and let it dl, then reconnect WiFi afterwoods, and surf. By then WiFi registers that I am using data stream and starts working again.

Hope this could help you try one more thing, since I had similar issues to yours.

Thanks so much for a fantastic ROM.
[HTC Sensation] marcos600rr:
ill try it and let you know will try it tomorow with full day ussage down loading i will post results at noon tomorow

[HTC Sensation] mexxxico:
Don't worry. Nobody so far has not brick the phone :)

After all, you can always revert to a previous state.
[HTC Sensation] vincepg13:
You sure? I'm about to flash and I already have this file there...just wondering if you can just delete
[HTC Sensation] mexxxico:
Reboot recovery and wipe dalvic-cache. It should help...

If this does not help, you can still in /data/app to find market folder and delete all on it.

After the restart Market app should work
[HTC Sensation] mexxxico:
Delete file and reboot

Wouldn't was the first script that I deleted from this folder
[HTC Sensation] GabrielSousa:
its NOT a good thing because that scripts has lot tweaks than dual cpu ON
[HTC Sensation] vincepg13:
Yer that's what I thought looking at it. Oh well hopefully baad will provide patch to flash back or ill just flash ROM zip again if this kills my battery
[HTC Sensation] GabrielSousa:
heres a file for flash, to revert to original 10optimize

;)
[HTC Sensation] vincepg13:
Cheers bro! They really need to get the thanks button on this app...ill hit it in the morning
[HTC Sensation] wltnkyl:
Love the performance so far...

I'll let ya know about battery drain later.

P.S. Best ROM I've used on any phone! Keep up the good work. Donating once I have access to a computer.
[HTC Sensation] the_scotsman:
Tried a few other ROMs yesterday, but just had to come back to this one, as it's simply the fastest out there.

One annoying thing I have with only this ROM is that the battery isn't shown to be draining, yet when I reset, it drops down several percent to where it should have been before the reset.

1- Went to bed with phone fully charged at 100%

2- Wake up, phone is still showing 100% which is rubbish.

3- Reset the phone, percent drops to 98%

4- Another reboot and it drops to 94%.

I know some of you will say "calibrate the battery..." but this doesn't happen on any other ROM, and I've flashed many of them over the last few days.

So what's causing this? Will it stop? :confused:
[HTC Sensation] jmcdonald58:
I noticed this also and I have had it happen on another build I have tried so far I reckon I flashed most of the sense builds only had this issue on 2 of em
[HTC Sensation] Kupfel:
battery stats are wiped as well if you do a full wipe. Just give it a couple of charge cycles, preferably completely charge and then completely drain and this will normalize.
[HTC Sensation] the_scotsman:
Yea, I understand that, but it doesn't happen on any other ROMs for me. Also, discharging a Lithium battery is not good for it.
[HTC Sensation] Kupfel:
Yes you shouldn't always let it discharge all the way but with your battery stats gone this is the most effective way to fix it. I had the same effect after getting my 1800mah mugen power battery and everything went back to normal after a few charge cycles. It is strange that this didn't happen for you with other roms. Did happen for me with revolution

hd as well.

Keep up the awesome work man, can't wait to see what next week's update brings!
[HTC Sensation] Pandemoniumone:
Press and hold on the post and a pop up menu will appear with "thanks" as an option. It was one of the additions in the latest update ;-)
[HTC Sensation] stevejau:
Interesting thing about battery calibration and stuff. I read so many people say discharge the battery fully and recharge, calibrate battery blah blah blah.

It is no surprise then that my mugen 1800 battery instructions clearly state in nice big wording. "Do Not fully discharge battery", now you would have to think that a company that makes batteries would have a fair idea about such things...don't you think?

Whatever anyones beef is about batteries/battery life one thing is for sure, they ALL discharge, fact of life. Personally i pay little attention to my battery, as i always have a means to charge while away from power outlet.

I carry a second battery and separate battery charge pack, so i can charge in the field, or paddock if your an Aussie, he he.

Truth be told I am yet to run out of juice whilst away, and rarely need the second battery or battery charge pack.

Just my 2 cents worth. (which is about $350.00 NZ)

Feed back for dual core zip

Ive been runnig it for about 2 hr and i must say that perfomance has increased very notable speed is ben notable alot of performance in internet browsing loading its insanly fast youtube as well facebook and market speed its notable the phone temperature its great not heating as usual batery life its a little shorter but is aceptable in fact i recomend to use the zip for dual core forse the phone just make a good change even the numbers of quadrant score increased and gaming its incredible smooth no lag at all......included a screenshoot of battery use

[HTC Sensation] tangcla:
I think by 'fully discharge' they mean run your battery flat, and then leave it idle to drain 0.5mA for the next two months. Remember these batteries have some intelligent circuitry in them to cut power when the voltage is too low - when your phone turns off from low battery there's still a bit of juice left to turn the phone back on.
[HTC Sensation] stevejau:
You are probably right on that score. Thats why i love these forums, so many people with so much info that we can share.
[HTC Sensation] skygear:
well fukc! I was excited that visual voicemail was working til I flashed the wifi fix. now it force closes immediately when booted -

a reinstall of the app solved the issue.
[HTC Sensation] Darkmx2000:
Alright when I read this and you say that the battery life is acceptable I'm confused??? You said you have been using it for about 2 hours and when i look at the screenshot it shows that you are at 51% battery so your on pace to completely discharge the battery within only 4 hours?
[HTC Sensation] marcos600rr:
Well i was using wifi gps facebook chat live profile browsing the web watched about 15 or more videos at you tube screen bright at 100% play a few games like nova 6 and modern combat 2 and a few calls was trying to kill the battery and she was still going ive try several rooms that kills batery even more fast only with normal use and no OC so i think thats the reason ive post was acceptable now you under stand the reason bro :) im still 25% by now with 3hr 58 minutes of exesive using the phone with multiple apps running
[HTC Sensation] rawrfische:
That's kinda weird. Maybe try reflashing the fix again and clearing cache/dalvik? Both my WiFi calling and visual voicemail are working fine after the flash.
[HTC Sensation] tigerz0202:
Just flashed the forced dual core zip and JESUS this ROM flies with it , I don't know about battery life or anything else yet but it makes thus ROM fly. Got a 2150 quadrant with stock kernel
[HTC Sensation] the_scotsman:
Just flashed the dual core patch. While I NEVER like to refer to Quadrant or other benchmarks, there is a significant increase in benchmark results after the patch.

Overall interface feels about the same though. Will monitor battery usage, but may not keep the patch if it uses a lot more battery, as I dont play games, so will hang off until the dual core is tweaked.

What does this patch do exactly?

Do we still have the frequency clocking down when it's not in use?
[HTC Sensation] GabrielSousa:
most of the time cpu1 is offline due power saving.

but when cpu0 is full load cpu1 goes online with ondemand governor.

this script keeps both cpus online from 1st boot all the time
[HTC Sensation] biglolz:
it would seem as though cpu1 is always online, rather than sleeping (disconnected/unplugged). scaling still works more, just that its 'interactive', which will chew a bit more juice and spend more time at higher clocks.

i agree with your findings so far...dont play games, feels the same. if anything the unit heats up faster, obviously with both cores online/more time at a higher clock.
[HTC Sensation] the_scotsman:
Ah ok thanks for that...so they are both enabled all the time, but they both still change clockspeed depending on load yes? if thats the case, this shouldnt increase battery usage by much.
[HTC Sensation] stevejau:
Flashed the dual core patch a while back and thus far i cannot see any difference in speed, nor battery drain.

Quadrant score is always around 2150, which for me is no different than without the patch.

This kind of reminds me of Intels super duper Hyperthreading technology when it first appeared, everybody wanted it..NEEDED it, and yet i couldn't see any improvement. Kind of akin to people wanting to run 64 Bit software on 32 bit hardware.

I always assumed that the software needs to be compatible with the hardware in order to fully take advantage of such things. Do we have such software for full dual core utilisation?

So for me, Dual core patch:

1. No noticeable speed increase

2. No noticeable battery drain (i say that because i use my phone all the time so my usage varies and therefore cannot provide an accurate battery test)

3: The whole thing possibly a placebo effect ?
[HTC Sensation] ddizzy81:
I downloaded ur beats add on and nothing changed. what do you think this is
[HTC Sensation] GabrielSousa:
do this on the shell

cat /sys/devices/system/cpu/cpu1/online

if you have "1" the script worked

if you have "0" the script didnt worked
[HTC Sensation] stevejau:
it says 1.
[HTC Sensation] Hoggles:
Baadz..... You're a baad man....

Holy Mother.... The dual core patch has my S4G mother F...in flying!!

There is no doubt .... 2.2.5 was the fastest to begin with, but with the DC patch, I feel this is what this device should feel like!

I could honestly care less if my battery dies in 2 hours.... It would be the fastest 2 hours of this phones life.....

Thanks!!

PS... Thanks Vlad.... I show "1" when I run the cmd in terminal emulator. It only confirms what I'm experiencing here!
[HTC Sensation] HashTagHell:
I fell out my damn chair laughing. :D
[HTC Sensation] biglolz:
where are you seeing this speed?
[HTC Sensation] Hoggles:
Everything......
[HTC Sensation] baadnewz:
thanks man
[HTC Sensation] biglolz:
games? apps? browsing?

we all understand the logic that the 2nd core rarely fires up, hence the load is always on the first, perhaps i dont use my phone enough to notice? perhaps i removed all the crap that places load...?
[HTC Sensation] xtcislove:
hey i flasched the dual core patch

is there a way to use ondemand governor?

And i looked what you use when the screen is off.

Both cpus are running when the Screen is off? Is this your liking? Or did you not added all the scripts from mike?

Is there a way to add them?

And can you maybe make a detailed changelog for your work or maybe put your "sources" online what you have changed exactly in your updates? I like to learn from you
[HTC Sensation] baadnewz:
i don't use or look @ mike's scripts. stop with mike already, if you like his work so much - flash Android Revolution HD.

You say you wanna learn but you can't look inside the zip ?
[HTC Sensation] xtcislove:
I have a look in the zip :P dont ***** me :) i like your work more....

if i have to look in the hole zip i have to compare the old ones... huge work or do you dont think so?

I like the whole work of our DEV´s and do we not benefit from each other?
[HTC Sensation] baadnewz:
so you like to learn but you don't like to work - cool, suggesting all the time to use mike's script because for some reason you think are better is not good for everyone. As i said if his rom is better for you don't use IC, but stop suggesting me to take pieces from his rom.

OTOH added a POLL, please vote
[HTC Sensation] vincepg13:
I only get reply, quote, share & more....and its not under more :/ and I got the latest one I believe.

Edit: wasn't up to date ;)

Oh and baad as much as I didn't want the dual core I decided to try it anyway ;) looking at your script....could I change CPU0's governor to say 'smartass'?
[HTC Sensation] show-p1984:
I don't understand the excitement about the dc patch... I just checked on my non-dc-patched phone. Both cores are online when the screen is on, one core is offline when the screen is offline. Only flaw I found is that the 2nd core runs with the ondemand governor, and not with smartass which will bring them out of sync.

I am currently altering the kernel source of htc to make it compileable, again, and will then build a test kernel for "normal" linux-like dual core behaviour. Including both cores at the exact same speeds and governors when stressed so they won't get out of sync.

We will see what that is saying about battery life and performance...

Btw, I just read through the whole Snapdragon tech specs... It's messy like hell.. damn Qualcomm's aSMP rendered all of the common OC scripts and apps useless -.- Or at least they will work on the first, but only apply partially to the second core.
[HTC Sensation] xtcislove:
why are you acting like this? i like to work to learn but you ahve to understand that it is much easier so see which pieces you updated. If not i always have to do a whole research on every update and i have to compare all files.

I dont think it is better -.- but there are pieces that are better! Like screen off profile where only cpu0 is running. Or do you find all the dual core "commands" on your own and not used the DEV-Notice Thread?

Your script "only" wake up cpu1 and put interactive governor on it. This is as sample as it can be.... dont like to say it is bad.

but we could gain a huge better battery life when cpu1 is not running when screen is off... i dont like to ***** about your work or something i like to help!

I tested whe scripts from mike on your rom and they are working, but they are not perfect so i think you can make it perfect..... i dont believe that you never have a look at other work from DEV´s and do all on your own.

You implemented supercharger scripts. So why not make mike´s scripts perfect for us?

Do you like to be the only one and the best and dont need any help or advice?

i cant understand why you are so agressiv to me... i dont btich your work i like to help -.-
[HTC Sensation] vincepg13:
Baad and Mike don't exactly see eye to eye, so I wouldnt mention him in this thread lol
[HTC Sensation] xtcislove:
I dont think what we have to patch the cores to be synchron they are designed to be asynchron

do you not think its better to control the asynchron thing better? I think the devs are trying this and the solution for now is only to run both cpu´s all the time which is bad for battery but good for speed. But i read this is only the solution for now and the devs are trying to go deep in the dual core control to take the beste performance/battery consumption of it?

Edit me if i am wrong but i understand it like this in the [Dev-Notice]
[HTC Sensation] vincepg13:
Does anyone use opera mobile? It won't work for me....starts up then just closes

Deffo worked on 2.2.3
[HTC Sensation] xl DIGITAL lx:
I am having a problem that I think the crt animation is causing it. Whenever I let me phone's screen timeout, it just goes into a hot reboot. Any idea why this may be happening?
[HTC Sensation] tissimo:
Dumb noob questions, but what does the 1.45 ruu flash? I have a tmous sensation shipped with 2.3.3 android, did the S-Off/revolutionary hboot, flashed a 2.3.4 radio.. is this the same thing, but in one step or does it do more? Trying to figure out my lack luster performance with the sensation.
[HTC Sensation] the_scotsman:
I've ditched the patch and gone back to original. makes no improvement for me. Happy the way it is for now.

Try removing the CRT screen and see if it still happens then...
[HTC Sensation] baadnewz:
i said i never looked / used mike's work. i do use other devs work - never said i did all alone ( hell you can even see in changelogs i give credits for every change i made and is not my work) and unlike others i dont claim myself that my work is the best, i let users decide '.

Your help means "get mikes script" .
[HTC Sensation] vincepg13:
Yer I agree with you mate. After all HTC obviously done this for a reason. Would just be kool if we could mess around a bit and change both cores governors, freqs with it sticking or changing the thresholds
[HTC Sensation] baadnewz:
you forgot about irc?

p.s. if you enforce smartass to cpu1 system won't boot
[HTC Sensation] undercover:
That looks like the way forward. I'm not a dev, so forgive me if question has obvious answer, but is it possible to divide the load equally between 2 cores after 101% percent load (lets say second core kickes in at 101%) instead of topping up CPU0 at 100% with whatever percentage on CPU1.
[HTC Sensation] umd:
Same here. Opera Mobile uses hardware acceleration. Because of broken 3D of 2.3.4 OTA, it won't work like other 3D games.
